Partsam 9-LED Cab Lights 5-Pack Clear Lens for Peterbilt and Heavy Trucks — IP65, Plug-and-Play Roof Marker

Partsam 5pcs 9-LED cab lights are a plug-and-play, high-output roof marker and running light set designed to replace incandescent fixtures on heavy trucks including Peterbilt 579, T680, T770 and T880.

These cab lights combine a compact, low-profile housing with nine bright LEDs and a clear polycarbonate lens to provide reliable roof marker illumination for large rigs. Built to withstand road vibration, moisture, and wide temperature swings, the assemblies are intended as straightforward replacements for standard cab/clearance lights on 12V heavy-duty vehicles, trailers, tractors and specialty equipment.

How bright are these 9-LED cab lights and what can I expect at night?

The nine LEDs in each unit deliver concentrated, consistent illumination with faster response than old incandescent lamps. Their pearl-shaped reflectors focus light outward and increase visibility across the cab roofline.

• 9 ultra-bright LEDs per assembly for strong rooftop visibility
• Reflector design improves light spread and on-road recognition
• Low power draw and rapid-on performance compared with bulbs

Are these lights weatherproof and durable for heavy-duty use?

Yes—each light is sealed with a polycarbonate lens and housing rated to IP65, so it resists water spray and dust intrusion encountered in highway and off-road conditions. The construction also tolerates vibration and temperature changes common to commercial truck operation.

• IP65-rated sealing against rain, road spray and dust
• Polycarbonate lens resists impacts and UV damage
• Robust housing suited for daily commercial use

How easy is installation—do I need special tools or wiring?

These Partsam cab lights are designed for plug-and-play installation in compatible models: they mount flush and use standard 12V connections, minimizing the time and tools required. In many cases, you’ll simply remove the old assembly and connect the existing wiring harness to the new unit.

• Flush-mount design for fast replacement of factory lights
• Compatible with existing 12V truck wiring harnesses
• Works as direct fit for Peterbilt 579, T680, T770, T880 and similar rigs

Which vehicles and applications are these lights compatible with?

Partsam’s 9-LED lights are made to fit popular heavy-truck models like the Peterbilt 579 and T-series cabs, but they also serve trailers, tractors, dump trucks and specialty vehicles that use similar rooftop marker fixtures. Confirm fit by comparing mounting dimensions and the truck’s 12V connector type.

• Direct-fit for Peterbilt 579, T680, T770, T880 roof/cab marker lights
• Suitable for 12V trailers, semi-trailers, tractors and dump trucks
• Ideal for replacing older incandescent cab running/clearance lights
